Series SCHIZOGNATH^E. 

 Order I. COLUMBJE. 



Fam. COLUMBIDJE. 



245. Columba palumbus L. Ring-Dove. 



Resident, generally distributed, abundant. Flocks of immi- 

 grants appear in October and November, their numbers 

 being dependent on the severity, or otherwise, of the 

 season. 



246. Columba livia Bonnat. Rock-Dove. 



Resident, very local, but numerous where it occurs. Breeds 

 in considerable numbers in the Flamborough range of 

 cliffs. They are also reported to breed in several inland 

 localities, as near Sheffield, where they are entirely absent 

 in winter, near Masham, near Pateley Bridge, and near 

 Richmond. 



247. Columba cenas Z. Stock-Dove. 



Resident, local, but common in most localities where it 

 occurs. This species is steadily increasing in numbers, 

 and gradually diffusing itself over the county, being now 

 frequent in localities where even ten years ago it was un- 

 known. Mr. Allis (1844) stated that the only Yorkshire 

 specimen he had seen was one in the York Museum, and 

 that the only locality in which it was known to occur at 

 that date was Sheffield, where they were reported as not 

 unfrequent. Now the stock-dove breeds in all parts of the 

 county, in localities too numerous to mention, but is least 

 frequent in the north-west. At Flamborough it breeds 

 plentifully in the sea-cliffs. 



248. Turtur communis Selby. Turtle Dove. 



Summer visitant, extremely local, and in very limited num- 

 bers. Breeds annually in Holderness and near Sheffield. 

 A few are observed in Eastern Yorkshire during the 

 autumnal migration. It is less frequent in the spring, but 

 on April 15, 1878, fifteen were observed at Flamborough. 

 In Western Yorkshire it is quite of exceptional occurrence.
